Sliding closure

Abstract

A device for manipulating a zipper comprising a slider with a base and a handle to which a pull is fastened. The pull is made of plastic and has portions which are so dimensioned that, when they contact the base and the handle of the slider, they are momentarily deformed, enabling the pull to pivot on the handle and subsequently to return to a stable position.

What is claimed is: 
     
       1. Device for the manipulation of a zipper closure comprising a slider (1) movable along a slide track and provided with a base (1a) and a handle (2) to which is fastened a pull (3) made of a plastic material and capable of pivoting longitudinally in relation to said handle (2), said handle (2) passing through an aperture (4) in said pull (3) separated from an end of said pull by a solid part (5) of said pull, said device comprising at least one hard point of contact between a first part (5a, 5b) of said pull cooperating with said handle (2) and a second part (6a, 6b) of said pull cooperating with said base (1a) of said slider, said hard point of contact being created by provision of a distance (b, f+g) between said first and second parts (5a, 5b; 6a, 6b) of said pull greater than a distance (a) between an inner edge of said handle (2) and said base (1a) of said slider, whereby said parts (5a, 5b; 6a, 6b) are momentarily deformed when in contact with said handle (2) and said base (1a) of said slider. 
     
     
       2. Device according to claim 1, wherein said hard point of contact is created in a longitudinal direction (L) of said pull. 
     
     
       3. Device according to claim 2, wherein said end of said pull (3) is located beneath said handle (2) and beyond said aperture (4) and is made of an elastic material, and wherein an edge (4a) of said aperture (4) is separated from said end of said pull (3) by a distance (b) which is slightly greater than said distance (a) between said inner edge (2a) of said handle (2) and said base (1a) of said slider (1). 
     
     
       4. Device according to claim 3, wherein said solid part (5) separating said aperture (4) from said end of said pull (3) has, in the area of said aperture (4), a dimension (c) which is less than said distance (b) by an amount smaller than said distance (a). 
     
     
       5. Device according to claim 4, wherein said solid part (5) of said pull comprises at least one side having a dimension (d) greater than a transverse dimension (e) of said aperture (4). 
     
     
       6. Device according to claim 5, wherein said solid part (5) comprises two sides having a dimension (d) greater than said transverse dimension of said aperture (4). 
     
     
       7. Device according to claim 1, wherein said hard point is created in a direction of said pull perpendicular to a plane of said pull. 
     
     
       8. Device according to claim 7, wherein said solid part (5) has a thickness (f), and wherein said pull comprises, on at least one lateral edge (6) of said pull, at least one projecting boss (6b) delimiting, in relation to said thickness (f), an increased dimension (g) such that said increased dimension (f+g) is greater than said distance (a) between said inner edge of said handle (2) and said base (1a) of said slider. 
     
     
       9. Device according to claim 1, wherein said pull (3) comprises an intermediate zone (7) which absorbs flexion and torsion forces and deformation exerted by a user of said device. 
     
     
       10. Device according to claim 9, wherein said intermediate zone (7) has at least one reduced section (8) affecting at least one of its width and thickness.
